Got your RFQ on the 87691 series flanges, and we've been running these through our machinery setups for about eight months now, so I can tell you they hold up well under that 300 bar working presure—we tested them up to 350 bar in house without any deformation, though I'd stick to the rated spec for routine use.
The chrome plating is actually better than most DIN-compliant options we've tried, as it resists the mineral oil mist in our shop without flaking, and the medium carbon steel gives them a solid feel when torquing down—just make sure your threads match (Metric or UNF, we usually stock both) because mismatching can cause leaks at the flange face.
Sizes from 1/2" up to 2" cover about 90% of our hydraulic lines, but if you need something for a submersible pump application, these aren't ideal since the round head design doesn't seal as well under constant water submersion—stick to a flat-faced style for that.
We ordered 500 pieces in 1" size last quarter, and the lead time was roughly 20 days or so form order to dock, with the packaging being plastic bags inside cartons which kept them scratch-free during transit, though we did have one batch where the chrome had a minor blemish—they replaced it without hassle.
The ROHS and SGS certs came with the shipment, and we had our QC run HPLC on a sample to confirm the carbon content, which matched teh COA at 0.45% carbon, give or take 0.02%, so the materail consistency is tighter than some generic imports we've seen.
Anyway, if you're looking at a monthly volume of 1,000 units or so, they can handle it easily with that 50,000-piece capacty, and we're planning to reorder next month for our hydraulic presses—just confirm your thread type and I'll send over DIN specs.
They're certified ROHS and SGS, so you're covered for environmental compliance and quality assurance on industrial machinery use.
Yes, we offer both Metric and UNF thread options. Just specify which one you need when placing your order.
We don't have a strict MOQ for stock sizes like 1/2" to 2", but for custom orders or special finishes, we typically ask for a minimum of 100 pieces.
Each connector is packed in a plastic bag first, then placed in a carton. This keeps the chrome plating scratch-free during transit.
Yes, all sizes from 1/2" to 2" in the 87691 Series are rated up to 300 Bar, as long as the operating temperature stays between -20°C and +120°C.
